vaguely. iirc correctly, since it's been a while since he talked about it. It has to do with apocalyptic or space travel(edit: he said neither of these after checking). MC is the last man. So there won't be NTR in his next game. That's pretty much all he's said. Was probably over a year ago now? It's been a while.
edit as i typed. I went back to see some details. He said it won't be as jokie. So it's probably more serious toned. He said it's going to be "contemporary reality with certain heightened details". that pretty much sums it up. This was back in May of last year, so almost a year now in 2 months.
I do wonder with how long ago that was, how much he's learned, new assets that have released since, the reception he's found from NTR, etc. If he's ever considered changing or doing a completely new idea for his next game.
